They will be moving away from each other at the same speed.

Explanation:

The final speed may be identical to the initial speed if the collision is perfectly elastic. The final speed will be zero if the collision is perfectly in-elastic.

In all likelihood, the final speed will be slightly slower than the initial speed.

Answer:

In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.

The correct answer is "121.36 meters and 2.40 MHz".

Explanation:

Given:

Red shift,

\(\frac{v}{c}=\frac{\lambda - \lambda_0}{\lambda_0} = 0.03\)

Wavelength,

\(\lambda = 125 \ meters\)

The observed frequency will be:

⇒ \(f = \frac{c}{\lambda}\)

      \(=\frac{3\times 10^8}{125}\)

      \(=24\times 10^5\)

      \(= 2.40\times 10^6\)

      \(=2.40 \ MHz\)

hence,

The Emitted wavelength will be:

⇒ \(\frac{125-\lambda_0}{\lambda_0} =0.03\)

   \(\frac{125}{\lambda_0}-1 =0.03\)

         \(125=1.03 \ \lambda_0\)

           \(\lambda_0=\frac{125}{1.03}\)

                \(=121.36 \ m\)

While walking down Madison Avenue, Thomas smelled smoke. Soon, Thomas saw flames leaping out of a third story apartment window. In a flash, Thomas saw another man run into the burning building and emerge, only a minute later, with a young girl in his arms. Witnessing this made Thomas feel hopeful about humans and our ability to help each other. Thomas felt the diffusion of responsibility

When there are additional witnesses or bystanders present, a person is less likely to accept responsibility for their actions or inaction, which is known as the "diffusion of blame" sociopsychological phenomenon.

When those who need to decide wait for someone else to take action in their place, responsibility is diffused. The more people participating, the more likely it is that no one will take action because they assume someone else in the group will probably take the initiative.

Diffusion of responsibility in the workplace can be seen, for instance, when an employee engages in offensive behavior toward another and they fail to report it because they feel it is not their place to do so.

The "bystander effect" and "diffusion of culpability" are two terms for the same psychological phenomena

Explanation:

Answer:

A.

Position-time graph:

The position-time graph for the ball punted vertically will be a parabolic curve, with the vertex at the highest point of the ball's trajectory. Since the initial position is zero, the curve will go through the origin.

Velocity-time graph:

The velocity-time graph will be a straight line that starts at the initial velocity and decreases linearly until it reaches zero at the highest point of the ball's trajectory. After that, the velocity increases linearly in the negative direction until the ball hits the ground.

Acceleration-time graph:

The acceleration-time graph will be a constant negative value, representing the acceleration due to gravity.

Motion map:

A motion map is a diagram that shows the position of an object at several specific times during its motion. For the ball punted vertically, the motion map would look like this:

|O|------|-------|------|-------|------|H|

O represents the initial position, and H represents the highest point of the ball's trajectory. The "|" symbols represent the position of the ball at regular intervals of time.

B.

To find the initial velocity of the ball, we can use the hang time and the acceleration due to gravity.

Hang time = 3.8 seconds

Acceleration due to gravity = -9.8 m/s^2

At the highest point of the ball's trajectory, the velocity is zero. Therefore, we can use the following kinematic equation to find the initial velocity:

hang time = (final velocity - initial velocity) / acceleration

Solving for initial velocity:

initial velocity = final velocity - (hang time x acceleration)

final velocity = 0 m/s

hang time = 3.8 s

acceleration = -9.8 m/s^2

initial velocity = 0 - (3.8 x -9.8)

initial velocity = 37.64 m/s

Therefore, the initial velocity of the ball was 37.64 m/s.

Calculating the mass of the block requires a bit of work. The formula for the volume of a rectangular solid is V = l*w*h, where V is the volume, l is the length, w is the width, and h is the height. Using the dimensions given, we can calculate the volume of the block as 30*80*60 = 144000 cubic centimeters.

The density of lead is approximately 11.34 grams per cubic centimeter. To calculate the mass of the block, we can use the formula m = V*d, where m is the mass, V is the volume, and d is the density. Plugging in the values we get m = 144000*11.34 = 1,634,400 grams or approximately 1.63 metric tons.

So, the mass of the block of lead is approximately 1.63 metric tons.

If an 8m long string is in its twelfth harmonic, the wavelength of standing waves on the string will be 1.33cm approximately.

The harmonics on the 12th fret are one octave above the open strings, while the harmonics on the 5th fret are two octaves above the open strings.

To arrive at the above answer, we deploy the "harmonic" wavelength principle which states that the "nth" wavelength is equal to the fundamental wavelength divided by n. That is:

λn = λ1/n

Answer:

Explanation:

To construct a graph of force due to gravity vs. distance, we need to collect data for force due to gravity (Fg) and distance (d) and plot the data points on a graph. From the information given, we have the mass of the object (1.23 kg) and the angle of the incline (35º), but we do not have any data for force due to gravity or distance. Without this data, it is not possible to construct a graph for force due to gravity vs. distance.

Since we don't have the data for force due to gravity or distance, it's not possible to calculate the work done by gravity using the data table.

Without the data for force due to gravity, distance, or time it's not possible to construct a free-body diagram or calculate work done by gravity. Also, we don't have the angle of the incline, so we cannot calculate the work done by gravity by multiplying it by the cosine of the angle.

It's important to note that work done by gravity (W) = force due to gravity (Fg) x distance (d) x cos(theta), where theta is the angle between the force of gravity and the distance.

It's also important to remember that work is a scalar quantity and not a vector, and it's the angle between the force and the displacement that is important to calculate the work done by gravity, not the angle of the incline.

Answer:

To solve this problem, we will use the equation for the net force on an object, which is:

net force = mass x acceleration

We can rearrange this equation to solve for acceleration:

acceleration = net force / mass

Once we have the acceleration, we can use the equation for the motion of an object under constant acceleration:

final velocity^2 = initial velocity^2 + 2 x acceleration x distance

We can rearrange this equation to solve for the distance required to stop the car:

distance = initial velocity^2 / (2 x acceleration)

Finally, we can use the equation for average velocity to calculate the time required to travel this distance:

time = distance / average velocity

Substituting the given values into the equations:

net force = 6000 N

mass = 1200 kg

initial velocity = 10 m/s

Using the first equation:

acceleration = net force / mass

acceleration = 6000 N / 1200 kg

acceleration = 5 m/s^2

Using the second equation:

distance = initial velocity^2 / (2 x acceleration)

distance = 10 m/s^2 / (2 x 5 m/s^2)

distance = 10 m

Using the third equation:

average velocity = (initial velocity + final velocity) / 2

final velocity = 0 (since the car is coming to a stop)

average velocity = 10 m/s / 2

average velocity = 5 m/s

Using the fourth equation:

time = distance / average velocity

time = 10 m / 5 m/s

time = 2 seconds

Therefore, the time required for a 6000-newton net force to stop a 1200-kilogram car initially traveling at 10 meters per second is 2 seconds.

Time needed = t = 20.83 s

Given

car speed = 85 km/h

truck speed = 73 km/h

Required

the time it takes for the car to reach the truck

Solution

When the car reaches the truck, the distance between them will be the same

x car - 250 m = x truck

General formula for distance (d) :

d = v.t

So the equation becomes :

85t-250 = 73t

12t=250

t = 20.83 s

Given the following data:

Scientific data:

To determine the quantity of heat (Q) that is required to increase the temperature at constant volume:

First of all, we would find the number of moles of oxygen gas.

\(Number\;of\;moles = \frac{mass}{molar\;mass}\\\\Number\;of\;moles = \frac{192}{32}\)

Number of moles = 6 moles.

At constant volume, the heat capacity for a diatomic gas is given by:

\(C_v = \frac{5}{2} R\\\\C_v =\frac{5}{2} \times 8.314\)

Heat capacity = 20.785 J/molK.

At constant volume, the quantity of heat (Q) is given by this formula:

\(Q = nC_v \Delta T\\\\Q=6 \times 20.785 \times 145\)

The magnitude of the resultant vector to round the answer to the nearest tenth, we look at the digit in the hundredth's place. If this digit is 5 or greater, we round up. If it is less than 5, we round down.

In the study of physics, we use vectors to represent quantities that have both direction and magnitude. It is often the case that we want to add two or more vectors together to obtain a single vector that represents the net result of these additions. The process of adding two or more vectors together is known as vector addition.The magnitude of the resultant vector is the length of the line that represents it on a scale drawing.

When we add two or more vectors together, the resultant vector is the vector that represents the net result of these additions. To find the magnitude of the resultant vector, we use the Pythagorean theorem, which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.

In the case of vector addition, the hypotenuse is the resultant vector, and the other two sides are the component vectors. If we have two vectors a and b, the magnitude of the resultant vector is given by the following equation:|R| = √(ax2 + bx2)where R is the resultant vector, a and b are the component vectors, and x is the angle between the vectors.

For example, if the answer is 12.345, we would round it to 12.3.

Answer: Earths sun will become a white dwarf. The sun will come to the stage of the white dwarf. And here's why, hydrogen which is what makes up the sun burns off and this takes away its fuel and this means it would become smaller. For the Sun to become a black hole it would have to be many times larger and implode and then collapse in on its self. The stages of a stars life cycle in order would be a stellar nebula(protostar) that collects and then heats up the hydrogen. Next is it just becoming and will become a stable star. After that is when our sun becomes larger and heats up. Then sun would be classified as a red giant. Then when it is done with it's slow and gradual growing it would shrink fast and become a white dwarf. But that is not the end because there is a theoretical thing that happens after a white dwarf and this thing that happens is called black dwarf star which is like a black holes littler cousin it is whatever is left of the white dwarf and emits no detectable light.
